Abstract
Dans un dispositif d'injection de carburant de réserve, le carburant sous pression peut être amené à deux réservoirs sous pression séparés (6 et 7) au moyen d'une pompe de suralimentation (1) et ces réservoirs sous pression (6, 7) sont reliés, par des dispositifs à soupapes séparées (16, 17) et par des conduites (14, 15, 19), à des buses d'injection. L'installation de réservoirs séparés (6, 7) permet d'éviter les superpositions de processus de préinjection et d'injection principale dans des cylindres différents.In a reserve fuel injection device, the pressurized fuel can be supplied to two separate pressure tanks (6 and 7) by means of a booster pump (1) and these pressure tanks (6, 7) are connected, by separate valve devices (16, 17) and by pipes (14, 15, 19), to injection nozzles. The installation of separate reservoirs (6, 7) avoids the overlapping of pre-injection and main injection processes in different cylinders.
